The Fish Shop is the home of Willy. It's located on the docks of the Beach, south of Pelican Town. If the player has not read the mail from Willy sent on Spring 2, then this shop cannot be entered. Although the door will unlock on Saturdays, the shop will be closed unless it is raining.
Willy offers a variety of fishing supplies inside, including rods, bait, tackle and crab pots, and more goods become available as the player increases their fishing skill. These items can be bought from the shop as soon as the appropriate skill level is achieved, without needing to wait until the next day. Willy will also buy fish or shells when he's behind the counter.
